SEPARABLE FASTENING.

Specification of Letters Patent.

Patented March 12, 1907.

Original application filed June '7, 1906, Serial No. 320,588. Divided and this application filed October 24, 1906. Serial No. 340,346-

T0 at whom it may concern:

Be it known that 1, WILLIAM B. MURPHY a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Separable Fastenings, of which the following is a specification.

The present Invention relates to the class of fasteners for gloves and the like sometimes called buttons which employ a socket member secured to one part and a balllike spring-stud secured to the other member; and the novel features of the present in vention reside in the spring-stud or ball-like member and its securing means.

The object of the invent1on embodied in the present applicat on, which is a division of my pending application, Serial No. 320,588, filed June 7, 1906, is to provide a spring-stud made from a cross-shaped sheet-metal blank and to provide means for securing the free ends of the arms constituting said stud to the material, as will be particularly hereinafter described.

In the accompanying drawings, which are on an exaggerated scale the better to illustrate an embodiment of the invention, Figure 1 is a plan of a stud-blank before it is rounded up into a globular form, and Fig. 2 is a side view of the stud after the next operation. Fig. 3 is a sectional view showing the stud clenched to the upper plate. Fig. 4 shows the said upper plate detached in perspective. Fig. 5 is a sectional view of the flanged securing-eye adapted for use with the upper plate. Fig. 6 is a sectional view, and Fig. 7 a plan, of the stud secured to the goods.

Referring to the principal views, the stud S, which is formed from the blank B, is resiliently compressible laterally, as is usual with the common ball-like studs of this class of fasteners, and it has tenons or clips 0 formed on the free ends of the several arms of the blank, Fig. 1.

It is necessary to secure the resilient stud S firmly to the goods and to brace it firmly in position without interfering with its spring like functions, and this is effected by the means to be described. A plate P, herein called the upper plate, is formed with a l bulb b on its upper side, the latter being integral with the plate, and about the base of the overhanging bulb b are apertures a, coextensive in number with the clips 0 on the stud S.

To connect the plate P with the stud S, the bulb b is passed into the hollow stud by spreading the branches or arms of the latter, and when it is inside the clips 0 are passed down through the respective apertures a in the upper plate and clenched on the under side of the latter. This is the construction seen in Fig. 3.

In applying the stud to the goods a flanged eyelet E, made from thin and ductile sheet metal and closed at its tip t, is passed up through the material or goods M from the back until its flange f rests against the material. The bulb b is then passed down over the protruding closed end of the eyelet and forced down by pressure on the plate P until the material M is tightly clamped, Fig. 6, between the plate P and the eyelet-flange The effect of this is to expand the end of the eyelet, which is housed in the bulb b, as seen in Fig. 6, and cause it to fit into and take the globular shape of the bulb 1;, thus forming a reinforce or lining for the bulb and securing the plate P firmly to the material M. The bulb b, which nearly fills the lower part of the hollow stud S and reinforces the clenches, gives the latter rigidity and firmness without affecting its springiness. The eyelet or hollow rivet E should of course be of the proper length to form the reinforce seen in Fig. 6 when the plate P and flange f clamp the material M firmly, and it is preferable that it should be thinner and more ductile than the plate P. The blank B is herein shown of a cross shape with four arms; but obviously this is not important. It may have any desired number of arms.

Having thus described my invention, I claim A device for the purpose specified, consisting of a resilient, laterally-compressible, globular stud, provided with a plurality of clenching-clips, an upper plate P, having an integral, bulbous portion 1), within the hollow of the lobular stud, and having apertures a,
